下面给个小例子，来验证一下error的捕获。

复制代码 代码如下:
public class TestCatchError extends Error{

private static final long serialVersionUID = -351488225420878020L;

public TestCatchError(){
super();
}

public TestCatchError(String msg){
super(msg);
}

public static void main(String[] args) {
try {
throw new TestCatchError("test catch error");
} catch (Throwable t) {
System.out.println("step in the catch ~");
t.printStackTrace();
}
}
}

运行结果：
复制代码 代码如下:
step in the catch ~
TestCatchError: test catch error
at TestCatchError.main(TestCatchError.java:23)
